    do the math, you'll see a difference. ive done it, its not close at all. off by 3 to 4 mpg.

    cold air, warming it upin the mornings all kill the mpg on the dic. may just be normal.

    I've also been wondering about the T Stat. The car runs at 180 deg. I think I read that they do better at 220?

    put a 195 in there, the car may not be warming up enough and its staying in closed loop, and killing mpg.

    your engine wants to be at 210 deg's.

    The AeroForce always shows 180 degrees when the car is hot. I'll try a new t-stat.

    If I put a 195 in, that will make it run at 220?
